CARPET-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 744,721, dated November24:, 1903. Application filed March 14, 1903. Serial No. 147,809. (Nomodel.)

To ctZZ whom it may concern/:-

Be it known that I, GEORGE A. COWGILL, a citizen of the United States,residing at of Ohio, have invented a new and us'eful'Oarpet-Gleaner, ofwhich the followingis a specification.

My invention relates to carpet-cleauers,and is an improvement on mycarpet-cleaner patented June 18, 1901, No. 676,460,and the cleaningdevices for which patent was applied for July 13, 1901, Serial No.68,209, and April 24,

1902, Serial No. 104,483.

The object of the present improvement is to provide improved means foractuating the heaters, for conducting the air-blast toand beneath thecarpet, and for preventing injury to the carpet by the heaters.

The invention consists in a fan-casing of peculiar construction,the'carpet being cleaned forming a portion of the front wall of thefancasing, heaters arranged in an enlargement of the casing, theair-blast passing downward between the heaters and thence under andbeyond the carpet being cleaned; also, in the means for actuating saidheaters and means for limiting the motion of the heaters, as hereinafterdescribed and claimed. p

In the accompanying drawings, Figure l is a side elevation of thatportion of my device containing the improvements herein described. Fig.2'is a plan view, a portion of the fan-casingbeing-broken away and insection. ing the interior of the chamber containing the heaters andmeans for preventing dust from escaping therefrom. Fig. 4 is aperspective detail view of a part of the beatershaft, one of theheaters, andattachments connected to the shaft. Fig. 5 is a detailperspective view showing the means employed to actuate the beater-shaft.Fig. 6 is a detail section, the spring-pressed roller and bracket beingin elevation. Fig. 7 is a detail perspective view showing the stop-pincarried by the beater-shaft. Fig. 8 is an enlarged detail viewillustrating the construction of the rocker-bar and showing the springsconnected at one end to the-bar and at the opposite ends to the casing.

In carrying out my improvements I employ base-beams A, on which aremounted the verby the heaters.

Fig. 3 is a detail sectional view showcarry the carpet A to be cleaned,all of which r is fully described in the applications heretoforementioned.

The fan-casing comprisesa cylindrical chamber B, arranged in the rear ofthe carpet to be cleaned. At its forward side this chamber communicateswith an air-passage B, having forwardly-diverging side walls, the part Bbeing at its forward end nearly the width of the carpet, the-carpetforming the front wall of the casing. Immediately below and having freecommunication with the passage B is the beating-chamber B closed bypermanent walls at the rear and sides and closed in front by the carpetbeing acted on From the lower partof this chamber extends a casing Bforming an air and dust passage beneath the carpet, and this passageopens into the dustchamber described in my former-applications forpatent andnot forming a part of the present im- B, mounted on a shaft Cand driven by belting 0, running to the pulley 0 Means are of Throughthe chamber B pass two parallel shafts D and D journaled in the frameA", as is the shaft C.

A belt E, running over pulleys E E drives a shaft E which carries apulley E The shaft D carries pulleys D D and D and the shaft D carries apulley D A belt E runs from the pulley E to the pulley D Suitable beltsrun from the pulleys D to D and D to the'pulley F, carried by the shaftF, on which is carried the roller actuating the carpet. A plurality ofcurved beaters G are arranged on the shaft D A compound-curvedrocker-bar H is rigidly secured to the shaft D adjacent one end, and ateach end of the rocker-bar is secured one end of a coil-spring H, theother end of thespring being secured to the side of the casing. Thetendency of these springs is to throw the beaters against the carpet.- Astop-pin H is secured on the shaft D adjacent the rockercourse providedto su pply air to said chamber.

bar, and when the shaft D is rocked the pin contacts with a stop Hhaving an inclined rubber face Hflwhich stop prevents the heaters fromtearing through or injuring the carpet.

Between the rocker-bar and the heaters the upper part of the shaft D iscut out, forming a flat surface J, to which is pivoted alaterally-projecting bar J, normally held at right angles to the shaft Dby a coiled spring J secured at one end to the bar and at the oppositeend to the shaft D The shaft D is transversely recessed, and aknocker-har K is rigidly secured in the recess extending on each side ofthe shaft and at right angles thereto. This bar is reduced in widthintermediate its ends, whereby the end portions K project laterallybeyond the intermediate outer side portion of the bar. This bar is soarranged that as the shaft D revolves the projecting ends of the bar Kwill strike the upper surface of the bar J, forcing it downward, rockingthe shaft D and drawing the heaters away from the carpet; but as soon asthe end K passes out of reach of the bar J the springs H immediatelythrow the shaft D in the opposite direction and bring the heatersagainst the carpet, the pin striking the stop H The construction of theparts are such that it is obvious that the shaft D will be rocked twicefor each revolution of theshaft D.

A lever L, carrying a pawl engaging a rackhar L, is located at one sideof the frame A and a cable L carried over suitable pulleys, extends fromthis lever to the bar J. By throwing the lever rearward the bar is drawnto one side outof the path of the knocker-har.

The shaft D is journaled in a bracket A on the frame A and extendstransversely just above the forward edge of the top of the passage B.This shaft carries a brush D which bears against the carpet and preventsthe latter from rubbing against the edge of the casing and also preventsair from the fan escaping between the edge and the carpet. To preventair and dust escaping into the space between the top of the passage B aroller M is arranged of a size sufficient to fill this space and isjournaled in spring-pressed hearings M, by which means it is heldagainst the carpet, so that no dust passes between the roller and thecarpet, and it also serves to keep the carpet in contact with theactuating-roller F. The belt 0 is driven from any suitable source ofpower, and it will he noted that by means of the lever L motion of therock-shaft D can he stopped without interference with any of the beltsor stopping any of the remaining shafts. It will also he noted that thedraft from the fan strikes the carpet just above the heaters and travelsdownward along the surface being beaten, thus carrying the dust away asrapidly as it is loosened from the carpet.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A device of the kind described comprising fan and beating chambers, apassage extending from the fan to the heating-chamber and openingdownward into the latter, a rockshaft carrying heaters arranged in theheating-chamber, a dust-passage leading from the said chamber, means forpassing a carpet in the path of said heaters, means for preventing airand dust from escaping between the carpet and the edges of theheating-chamber, a fan in the fan-chamber, and means for driv ing same.

2. A carpet-cleaning machine comprising a beating-chamber, adust-conduit, leading forwardly from the lower portion of theheating-chamber, a spring-pressed roller above said conduit adapted tobear on the carpet and prevent dust escaping into the space between thecarpet and conduit, means for heating said carpet, and means for passingan air-blast through said beating-chamber.

3. In a device of the kind described, a heating-chamber, heatersarranged therein,means for passing a carpet vertically before saidheaters, means for directing an air blast against the carpet above theheaters, an air and dust discharge conduit leading from theheating-chamber below the heaters, said airhlast passing downward alongthe surface of the carpet between the heaters, and means for actuatingthe heaters.

4. The combination with a beatingchamher adapted to receive a carpet, arock-shaft arranged therein, curved heaters on said shaft,spring-actuated means for throwing said heaters toward the carpet, a barnormally held at right angles to said shaft, a parallel revoluhle shaft,a knocker thereon adapted to engage the bar on the rock-shaft and drawthe heaters away from the carpet, means for drawing the bar from thepath of the knocker, and means for limiting forward movement of theheaters.
